MOLD.

Specification of Letters Patent.

Patented July 8, i915.

Application filed October 2,1914. Serial No. 864,658.

To all whom it may concern Be it known that I, JOHN KnssLnR, a citizen of the United States, residing at Marshallton, in the county of New Castle and State of Delaware, have invented new and useful Improvements in Molds, of which the following is a specification.

This invention relates to a mold for the manufacture of Babbitt or other soft metal supplemental jaws for use upon the permanent jaws of machinists vises to hold finished work.

The main object of the invention is to provide a two-part mold of novel construction whereby soft metal supplemental aws of the character described may be easily, quickly, conveniently and economically made.

A further object of the invention is to provide a mold whereby supplemental jaws with relatively thick and thin clamping and body portions may be produced, so that the jaws may be bent and mounted upon the v1se to obtain square clamping faces.

The invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawings in which I Figure l is a perspective view showlng the mold sections assembled as in use. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a vertical transverse section thereof. Fig. 4 is a top perspective view of the lower mold member. Fig. 5 is a similar view of the upper mold member. Fig. 6 is a bottom perspective view of the upper mold member. Fig. 7 is a perspective View of a soft metal supplemental jaw of a kind produced by the mold. Fig. 8 is a perspective view of a vise,-showing one of the supplemental jaws applied and another in process of application.

The mold comprises a lower mold section 1 and an upper mold section 2, which sections are of oblong rectangular form in plan. The bottom section body plate 3 having at one of its longitudinal edges an upright forming a wall 4 preferably provided upon its upper edge with an indicating gage or scale 5. Along its opposite longitudinal edge the plate 3 is formed with a longitudinally extending sup porting ri 6, ofmaterially less depth than said wall 4. The rib 6 intersects, at one end of the plate 1, a transverse rib 7 of corre- 1 consists of a base or.

sponding depth thereto, and between the opposite end of said rib 7 and the adjacent end of the wall 4 is formed an end flange or forming wall 8, coextensive in depth with the wall 4. By the construction described the bottom mold section is formed to present a shallow mold chamber open at the opposite end of said mold section, and having at one end the raised walls 4 and 8.

The upper mold section 2 corresponds in general form and contour to the mold sec tion 1 and comprises a body portion or plate 9 having at one side a vertically disposed forming wall 10 and at one end a depending transverse rib 11 along its end edge and a flange 12- projecting beyond the rear face of the adjoining end of the wall 10, said wall 1.0 and flange 12 being coextensive in general dimensions with the wall 4 and flange 8 of the mold section 1. The rib 11 is of a depth corresponding to the ribs 6 and 7 and terminates short of the longitudinal edge of the plate 9 opposite the wall 10, so that a recess 18 is provided to adapt such edge of the plate 9 to overlap and rest upon the rib 6 when the mold sections are assembled.

By reference to Figs. 1, 2 and 3, it will be seen that the mold sections are assembled for use by disposing the section 2 upon the section 1 in such a manner that the wall 10 lies in contact with the flange 8 and the flange 12 in contact with the Wall 4, thus disposing the walls 4 and 10 in spaced relation to provide a mold chamber 14, while the rib 11 rests upon the plate 3 and cooperates with the ribs 6 and 7 to form a chamber 15 intersecting the chamber 14 of less relative thickness than the same. V hen the mold sections are thus applied the outer side and unflanged end. of the plate 9 of the mold section 2 will respectively rest upon the ribs 6 and 7, thus holding the mold sections in proper relation and in sliding contact so that said sections may be relatively adjusted to space the ribs 7 and 11 and the flanges S and 12 to the desired extent to vary the effective length of the L-shaped mold cavity formed by the chambers 14 and 15 for the production of vise jaws of different length, the degree of adjustment being determined by the gage or scale 5. The molds being thus assembled, the Babbitt or other metal employed is poured in a molten condition into the l.-shaped mold cavity through the vertical chamber 14 and allowed to cool in the mold, whereby a supplemental vise the vise 20 and clamped together by said jaws 19, after whichthe thin body plates 17 of the supplemental jaws are hammered :down from a straight horizontal position over the curved faces of the jaws 19, and the free corner portions of said plates 17 offset or bent downward into engagement with the shoulders 21 of the jaws 19, as indicated at 22, thus fastening said supplemental jaws in position.

By the construction described soft metal jaws having thick clamping portions are provided upon the main jaws for gripping and holding finished work without injury, and these supplemental jaws may be readily made with facility by means of my improved mold, and also applied and removed in a ready and convenient manner. By so constructing the supplemental jaws with thickened jaw portions and thin body portions disposed at right angles to each other and subsequently bending the body portions to conform to the curved faces of the main jaws 19, the straight right angular corners between the jaw portions 18 and body portions 17 are preserved, a matter of distinct advantage in clamping objects and a condition impossible to secure when a straight piece of soft metal is bent and hammered over upon the main jaws to produce a supplemental jawa Inasmuch as the mold is simple of construction and inexpensive of production, it will be evident that the users of Vises of the character described may be furnished at a low cost with a mold which I Copies of this patent may be obtained for nail edges,

may be readily employed by any machinist for the productions of jaws of the character described.

I claim 1. A mold for use in the production of soft metal supplemental jaws for vises comprising a pair of cooperating oblong rectangular mold sections, one of said sections having ribs along one of its longitudinal edges and one of its end edges, a forming wall along its opposite longitudinal edge, and a flange at the intersection of said wall and the said end rib, and the other mold section having cooperating elements whereby when the mold sections are assembled an L- shaped forming cavity will be produced, one of the portions of which cavity is of less forming depth than the other.

2. A mold for use in producing soft metal supplemental jaws for vises, comprising a bottom section consisting of a rectangular plate having a rib along one of its longitudia rib along one of its end edges, a vertical wall of greater depth than the ribs along its opposite longitudinal edge, and a vertical flange between and at the intersection of one end of said wall and the said end rib and corresponding in depth to the wall,'and an upper mold section comprising a rectangular plate having a vertical. forming wall along one of its longitudinal edges, a depending rib along one of its end edges and an outwardly extending transverse flange at the intersection of the wall and rib for cooperation with the bottom mold section toproduce an L-shaped forming cavity,

the horizontal portion of which is of less depth than the width of the vertical portion thereof.

In testimony whereof I afiix my signature inpresence of two witnesses.
